VIDEO: Gastao Elias celebrates the Cristiano Ronaldo way after upset win in Stockholm

Gastao Elias caused a major upset on Thursday at the Stockholm Open in Sweden as he ousted top seed Gael Monfils to advance to the quarter-finals of the ATP 250 event here.

The Portuguese journeyman, ranked 61st in the world rankings, held his serve throughout the 79-minute encounter to pull off a stunning 7-6 6-1 victory against his 7th-ranked French nemesis.

However, the highlight of the match was the celebration that ensued. Elias acknowledged the crowd before emulating his countryman, football superstar’s Cristiano Ronaldo trademark style.

When asked about it in a post-match chat, he said, “I told someone before the match that [I] would do this celebration if he could win. And so it was. It was a great day and the best date I’ve ever played in my life.”

Meanwhile, Elias is scheduled to lock horns with sixth-seeded American Jack Sock in the last-eight stage.
